Wayson, Neerlham, Mass, assignor to Merriman, Inc, a corporation of Massachusetts Filed Apr. 14, 1964, Ser. No. 359,667 7 Claims. (Cl. 57-120) This invention relates to the textile industry and is particularly concerned with spinning rings.

In certain types of spinning operations, such as the production of fine yarns, it is necessary to use small spinning rings and correspondingly small, lightweight travelers to produce the best results. If the traveler is to be very light in weight, it must be reduced in length, as the diameter of the wire from which the traveler is made cannot be reduced below a certain figure lest the traveler lose its necessary rigidity. Thus if a traveler is to be short in length, the dimension of the spinning ring, Whether vertical or horizontal, on which the traveler is positioned must be correspondingly reduced.

Heretofore, in the practice of spinning fine yarns horizontal rings have always been used, as it has not been practical to use vertical rings with vertical style travelers because of the virtual impossibility of piecing up. In the use of small vertical rings, difficulty arises after the vertical dimension of the vertical type spinning ring is reduced to, for example, a dimension of inch or less, which is in textile mill parlance a No. 2 flange. In such cases, the vertical dimension of that part of the supporting ring holder that enters the circumferential groove in the ring will be in the order of .040 inch, leaving only approximately inch of the spinning ring extending above and below the surrounding holder.

With such small dimensions, it is obviously very diflicult, if not impossible in production, for the operator in starting up to piece up or thread up, which includes the placing of the yarn in position within the traveler. The reason, of course, is that, considering the very small space between the upper surface of the holder and the end of the traveler, the human finger is just too big to enable the yarn readily to be hooked in place under the traveler.

Accordingly, because of the problem just presented, it has heretofore not been considered feasible to reduce vertical ring and traveler dimensions below a point where ready introduction of the yarn into the traveler could be accomplished by the ordinary spinning frame operator.

With the foregoing in mind, the present invention has for its object a novel ring holder construction designed to facilitate introduction of the yarn into the traveler r used on a vertical ring as small as or even smaller than comparable horizontal type rings.

The invention also includes a cooperating split ring holder of small dimensions having included as an integral part thereof a novel type of oil reservoir and related means for feeding the oil to the entire ring so that when the ring is made of sintered powdered metal the lubricant may readily reach 'all surfaces of the ring. It is to be understood, however, that the novel holder may also be used with solid steel rings.

These and other objects of the invention will become more apparent as the description proceeds with the aid of the accompanying drawings in which:

FIG. 1 is a plan view of a holder and a vertical type spinning ring mounted therein;

FIG. 2 is a greatly enlarged section taken on the line 2-2 of FIG. 1 showing the cut-away nature of the holder at that section to provide the necessary space Patented May 9, 1967 below the traveler to facilitate introduction of the yarn into the traveler; and

FIG. 3 is a vertical section taken on the line 3-3 of FIG. 1 showing the oil reservoir and related wicks and the normal limited distance between the traveler and holder.

Referring now to the drawings, the holder is illustrated at 2. It may be attached to the spinning frame in any convenient manner which need not be illustrated herein.

The holder is split as at 4 so that upon removal of the clamping screw 6 it may be spread apart sufficiently to introduce therein the associated very small vertical type spinning ring which carries thereon for sliding move ment thereabout during the spinning operation a cor respondingly small traveler 10.

As can be seen in FIGS. 2 and 3, the problem can be better appreciated when it is realized that in small rings of the type involved herein the vertical thickness of holder 2 as indicated at A is in the order of .25 inch while the vertical dimension of the flange B that holds the ring is in the order of .040 inch. The dimensions of the ring at C and D above and below flange B may be as little as .058 inch. Thus the difficulty of introducing the yarn under the end E of the traveler 10 can be appreciated.

In order to produce more working space for the operators finger as he attempts to introduce the yarn into the traveler, the upper surface of holder 2 has been cut away at the area indicated in FIG. 1 at 12 to produce a very thin fiat section at 14 and a thicker portion 16 with a sloping upper surface 18 shown plainly in FIG. 2.

The horizontal section 14 will in the construction shown have a vertical dimension of approximately .010 inch. While this section is so thin that if continued about the periphery of the ring its strength would be in question, nevertheless its circumferential length is not long and this, coupled with the fact that that part 19 of the holder adjacent the thin section 14 and within the ring groove remains intact, leaves the holder with suflicient strength to support the ring. On the other hand, by greatly reducing the thickness of the area 14 immediately adjacent the ring and providing the sloping surface 18 a space is created at F between the upper surface of section 14 and the end B of the traveler of sufficient vertical dimension to facilitate the introduc tion of the yarn in the traveler in starting up or piecing up. The circumferential extent of the depressed or cut away area 12 will permit the reception therein of the operators finger during thenormal positioning of the yarn under the traveler, but, to preserve the strength of the holder, should preferably not exceed If the ring 8 is made of sintered powdered metal, oil may be supplied thereto in the following manner: In the holder 2, a circular cavity 26 receives an oil cup 27 formed of a cylindrical part 28- in forced fit relationship. A shoulder 30 rests on the upper surface 32 of holder 2 and connects with a larger cylindrical upper port-ion 34. The top is closed by a cover 36 having a centrally located hole 38 through which oil may be introduced.

Within the oil cup are located a pair of conventional oil metering felts 40 and 42 between which is a wick 44 which leads through an oil passage 46 to the ring 8.

The oil passage 46 may be conveniently formed through the use of a thin circular cutter which will cut a semi-circular groove 48 shown in FIG. 1 of suflicient depth to pass through the holder flange at 50 and a portion of the cylinder 28.

The ring 8 has a circumferentially extending groove 52 in which in close fit resides the holder wall of which the section 19 is a part. A subsidiary groove 54 is in the vertical wall of groove 52 and positioned therein are one or two turns of wick 44 around the entire perriphery of ring 8.

From the foregoing explanation of the invention, it will be seen that I have made possible the use of a vertical type ring and associated traveler far smaller than has heretofore been considered possible. Thus it is now no longer necessary to use horizontal type rings when small sizes are required.

This invention is equally applicable to fine yarn twisting and, when the term spinning ring is used, it is intended to cover twisting rings as well.

It is intended to cover 'all changes and modifications of the example of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.

I claim:

5. The combination of a vertical type spinning ring and holded in which the spinning ring is of such small vertical dimension that the upper end of the traveler adjacent the normal upper surface of the holder is so close thereto as to make positioning of the yarn within said traveler by the operator economically unfeasible, the said normal upper surface of said holder being flat all around the ring except at a small area of limited circumferential extent immediately adjacent the ring in which area the upper surface is depressed to increase substantially the vertical distance between the said depressed surface and the upper end of the traveler, said depressed surface being of small radial dimension and connecting directly with a larger area sloping downwardly and outwardly, whereby when the traveler is located adjacent said area an operator, holding the yarn in conventional manner and with his finger against said sloping portion, will be able to position the yarn readily under the hook of the traveler.

6. The combination of a vertical type spinning ring and holder, the spinning ring having an external circumferential groove thereabout with a vertical dimension of about .040 inch, said holder having an internally extending annular flange of substantially the same vertical dimension as said groove and fitting in said groove to support said ring, the said flange over a limited arc having a depressed upper surface immediately adjacent the said ring so that the flange thickness over said are is reduced to approximately .010 inch, an outwardly downwardly sloping area extending from the outer boundary of said depressed surface, the said surface providing a segment along said ring where the vertical distance between said depressed surface and the upper end of a traveler on said ring is great enough to provide for relatively easy introduction of yarn into said traveler as distinguished from the small distance elsewhere about said ring between the upper surface of the holder and the upper end of the traveler which practically precludes introduction of yarn into the traveler.
